If He(g) has an average kinetic energy of 6430 J/mol under certain conditions, what is the root mean square speed of O2(g) molecules under the same conditions

answer: 7270

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

x = 3 ± √(5+y)
